  • One of known such beverage extractors has a cylinder for accommodating a rawmaterial and a piston for compressing the rawmaterial accommodated in the cylinder, wherein the raw material contained in the cylinder is compressed with the piston by moving either the cylinder or the piston and a beverage is extracted by supplying hot water into the cylinder.
  • a hot water feed pipe for feeding hot water into the cylinder or an extract pipe for circulating the extract liquid is connected to the moving cylinder or piston.
